Selected RD1 peptides for active tuberculosis diagnosis: comparison of a gamma interferon whole-blood enzyme-linked immunosorbent assay and an enzyme-linked immunospot assay.
We recently set up a gamma interferon (IFN-gamma) enzyme-linked immunospot assay (ELISPOT), using selected early secreted antigenic target 6 (ESAT-6) peptides, that appears specific for active tuberculosis (A-TB). However, ELISPOT is difficult to automate. Thus, the objective of this study was to determine if the same selected peptides may be used in a technique more suitable for routine work i...
متن کاملEnzyme-linked immunospot assay (ELISPOT): Quantification of Th-1 cellular immune responses against microbial antigens.
Adaptive immunity is an important component to clearance of intracellular pathogens. The ability to detect and quantify these responses in humans is an important diagnostic tool. The enzyme-linked immunospot assay (ELISPOT) is gaining popularity for its ability to identify cellular immune responses against microbial antigens, including immunosuppressed populations such as those with HIV infecti...
متن کاملGamma interferon-based immunodiagnosis of tuberculosis: comparison between whole-blood and enzyme-linked immunospot methods.
The gamma interferon secretion levels of 52 adults whose T cells had been stimulated with the Mycobacterium tuberculosis antigens CFP-10 and ESAT-6 were measured by enzyme-linked immunospot methods and a whole-blood-based assay. The test results correlated well (r = 0.689, P < 0.0001). Its simple format and use of only small volumes of blood make the whole-blood assay suitable for pediatric pra...
متن کاملImmune monitoring technology primer: the enzyme-linked immunospot (Elispot) and Fluorospot assay
Description of the technology Elispot is a workhorse for functional analysis of single immune cells. Originally established for the enumeration of specific antibody-secreting B cells in 1983 [1], the technology has been expanded to the analysis of T cells, NK cells and monocytes. The assay is typically carried out in 96 well plates with a nitrocellulose or PVDF membrane, which is coated with an...
متن کاملAccuracy of enzyme-linked immunospot assay for diagnosis of pleural tuberculosis: a meta-analysis.
Current methods for diagnosing tuberculous pleurisy are poor. Some studies have explored the diagnostic value of a pleural effusion enzyme-linked immunospot (ELISPOT) assay, but its accuracy remains controversial. Therefore, we performed a meta-analysis of the existing evidence on the ability of the ELISPOT assay to diagnose tuberculous pleurisy. We systematically searched PubMed, Google Schola...
